The applicator may use any settings which yield the best results for the individual spraying technique and current weather conditions. Brightside® Polyurethane is best applied in thin coats. Do not apply heavy coats as this will affect dry through. Failure to follow proper dry times carefully will cause improper drying, wrinkling and loss of adhesion. Avoid painting in direct sunlight.

  1. Interlux Brightside paint 5 Star Review

    Posted by on Mar 8th 2018

    This paint is great for the amateur boat builder/restorer. I have used the roll and tip method to paint the sides of a Catalina 25 and Catalina 27. Several years later the boats still look freshly painted. I am now painting another boat with Brightside.

  4. Interlux brightsides 2 Star Review

    Posted by on Feb 20th 2017

    I am not a professional boat painter but a very capable do it yourselfer, having built and painted three boats and restored a fourth. I am currently restoring a finned fiberglassic(1959 Glass Craft Imperial) when the West Marine manager told me about Interlux Brightsides, saying you could roll and tip it, probably 3 coats and not have to wet sand, compound and polish and end up with a finish that looked like it had been sprayed professionally...Who wouldn't be intrigued...I just completed my 10th coat sanding with 320 between coats as the label instructs. Started with one quart of their Interlux Pre-coat, one quart of their 333 thinner and two quarts of their red Interlux Brightsides. So far I've actually used 5 1/2 quarts paint and I also had to buy a second quart of primer and 333 brushing thinner. I've talked with Interlux reps twice by phone thinking I just wasn't doing things correctly ass I just wasn't getting that sprayed on look no matter how much I thinned the paint. If I thinned it right so it leveled out nicely on the bow than it would run and sag badly on the vertical areas like the fins and splash well, this would be okay if I could just sand and repain the area with runs and then wet sand compound and polish everything to blend it all in...but I can't. Brightsides is not supposed to be sanded or polished at all after last coat, technician said it ruins the gloss, uv protection and life of the product. I am very disappointed that I purchased 5 1/2 quarts of this product' (three from you) thinking I just had to get the hang of it, in talking to the technicians I explained I am painting in my heated (70 degrees) where weather and humidity are not a factor, also when I thin it down so It really levels out I see the sanding scratch marks right through the paint! If a person really wanted (show quality) I would strongly recommend against this product and recommend a paint that could be compounded and polished. I just want my money back or I want you to send me some paint that I can wet sand, compound and polish to a great finish. Even the last tech I talked to suggested I thin it significantly more and do three or more coat without sanding between coats and repainting before previous coat has dried. That may work but it is exactly counter to everything on their website and I wasn't about to buy any more of this.

  5. Very good paint 5 Star Review

    Posted by on Dec 30th 2015

    This is the first boat I have designed and built. I chose Interlux so I would have the ability to buy paint in any port. I found it to be very good. If you prep properly, the pain looks like it was sprayed on. Well, at least mine does. Don't overdo the brushing liquid. I found that for the first coat you don't need the brushing liquid. Sand that then add 2 percent and do the second coat. For the third coat add 4 percent. That is what I found that works in Florida. Up north it is probably more.

  6. Great paint 4 Star Review
